IDEA NOTE Multi-step stroke is achieved with minimum actuation.

The use of an eccentric tapered cam along with an actuator allows for a multi-step stroke to be possible.

IDEA NOTE Sets three positions via stroke and cam.

Cam rotation and linear stroke allow for three different positions to be set.

    CAD Data Limitations

    1. Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
      You will need to edit the Data so that it meets your specific design conditions.
    2. Unit assembly Data consists of some sub-assemblies.
      It is configured so that each sub-assembly unit can be used as it is or edited.

      3. * The part in the frame is a sub-assembly unit.

    3. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    4. The Data including the third-part components are made by the Company.

       It is configured so that each sub-assembly unit can be used as it is or edited.

Application Overview

Purpose

  • To transfer workpiece using multiple steps.
  • [Operation]
    A linear movement/rotation actuator is used as a drive to preform a multi-step stroke with the help of an eccentric tapered cam.
    The details of the multi-step stroke are shown below.
    Position 1: Initial state in which the actuator is not operated.
    Position 2: State in which the eccentric cam is rotated by 180° by the rotary stroke of the actuator.
    Position 3: Tapered cam is moved 29.8mm by the linear stroke of the actuator.

    A condition in which the center of the rotation of an object is located at a different position than the center axis that passes through the center of gravity of the object.

Target workpiece

  • Shape: circuit board carrier, tray.
    size: W48 x D80 x H54mm.
    weight: 0.6kg.

Design Specifications

Operating Conditions or Design Requirements

  • Outer dimensions: W135 x D500 x H232.5mm
  • Vertical stroke: 30mm
  • Cylinder stroke: 29.8mm

Required Performance

  • Weight: 1.1kg.

Selection Criteria for Main Components

  • Swing cylinder.
    • Torque of 0.4 N·m or more at oscillation angle of 180 degrees.
    • Thrust in horizontal direction of 30 N or higher.

Design Evaluation

Verification of main components

  • Verify if the cylinder can withstand the load torque and weight of the workpiece.
  • Lifting thrust.
    • Conditional value: workpiece mass W1 = 1.1 kg, gravitational acceleration g = 9.8 m/s ².
      Cylinder thrust: F1 = 196 N, angle of eccentric cam: θ1 = 20°
      Cylinder lifting thrust: F2 = F1/tan20° = 196/tan20° = 538.5N
      Load F3 = Wg = 1.1 x 9.8 = 10.1N
      F2＞F3.
  • Torque.
    • Conditional value: cylinder effective torque T1 = 0.422 N·m (air pressure 0.4 MPa),
      Maximum distance from eccentric cam to load on the drawing when cylinder has stroked by 29.8 mm L1 = 0.0325 m
      Load torque T2 = F3 x L1 = 0.328 N·m
      T1＞T2.

Other Design Consideration

  • By setting the length of the eccentric portion of the cam as twice the length of the vertical stroke produced by the taper, equal stroke is enabled.
